MATHSAT - materialize heap space attributes.

Operand 1 - Spcp to the materialize template
Operand 2 - Spcp to heap identifier
Operand 3 - Attributes to materialize

When operand 3 is X'00', the 128 bytes of heap space attributes are 
materialized.
When operand 3 is X'01', the 128 byte attributes followed by a 16 byte Mark 
Template Information.
When operand 3 is X'02', you get the 128 header, the 16 byte Mark template and 
then 48 bytes for each allocation ( the allocation template )

But when I run the instruction with the following:
HsId returned by CRTHS
A single ALCHSS has been run on the heap space.
Operand 3 = X'02' - materialize header, mark and allocations

I get 176 bytes returned. ( value in Template size - number of bytes available 
for materialization ).
The 16 byte Mark Template Information is missing. The 48 bytes of recurring 
Allocation Template starts immed after the 128 byte allocation template header. 
( 128 + 48 = 176 ).

Can someone confirm this?  I am on v4r4. My MIFR manual is V4R4 also.

Thanks,

Steve Richter
